LATCH FOR SLIDING DOORS.

SPECIFICATION forming part of Letters Patent No. 275,149, dated April 3, 1883.

Application filed October 31, 1882.

To all whom it may concer-n Be it known that l, ENos M. CLOUGH, ot Lake Village, in the county ot' Belknap and State ot New Hampshire, have invented an Improved Handle and Latch for Car-Doors; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanyingdrawings, making part of this specication.-

Figure 1 is a side view ot' a car-door as mounted on a side of a freightcar and provided with my improved handle and latch; Fig. 2, a section ot' the door and handle in a plane indicated by the line x Fig. l; Fig. 3, asecton in a plane indicated by the line y y, Fig. 1.

Like letters designate corresponding parts in all the gures.

My improved handle and latch are applied to sliding doors, and are intended especially for the sliding doors of freight-cars, ordinarily to be used on the inside thereof, so as to be selflocking and self-unlocking by merely acting on the handle to close and open the door. The objects to be gained by the construction are simplicity and cheapness of construction, strength and durability in use, and convenience and certainty in action.

For the latch A, I employ a simple straight elastic strip of metal attached to the door B at a a by screws or bolts, and having a hook or shoulder-catch, b, tocatch over a catch-bar, c, on the door-jamb O. l

The handle D is pivoted at its two ends to bearings d d, projecting outward from aplate, E, which is secured to the door by screws c o (Model.)

or otherwise. In order to unhook the latch A, a projection,f, on one end of the handle extends therefrom back behind the latch, so as to force the said latch outward by the tilting or rocking of the handle in the proper direction, which is the direction in which the hand presses the handle in the act of pushing back and opening the door. The handle is allowed to rock in its bearings in that direction far enough to raise the latch away from the catchbar, and in the other direction far enough to allow the latch to catch completely over the catch-bar. Since the sliding of the door requires a considerable exertion of force, this handle should be strong and firm, notwithstanding this slight rocking movement. I therefore widen both bearing ends g g thereof in both directions into the shape ot' rockers, as shown, so as to form stops ot' considerable length and abundant strength to bear against the sides ot' the plate E. Thus I gain fully all the purposes and advantages above set forth.

What I claim as new, and desire to secure by Letters Patent, is-

The combination of the iiexible elastic latch A, the plate E, provided with bearings d d, and the rocking handle D, provided with the latch-lifting projection f and the doubly-extended stops g g, substantially as and for the purpose herein specified.
